COP-TU BE.

SPECIFICATION forming part of Letters Patent No. 235,196, dated December7, 1880.

Application filed November 13, 1879.

To all whom it may concern Be it known that 1, ALBERT BALL, of Glaremont, in the county of Sullivan and State of New Hampshire, have invented anew and Improved (lop-Tube; and I do hereby declare that the followingis a full and exact description of the same, reference-being had to theaccompanying drawings, and to the letters of reference marked thereon.

The improvement in woven, braided, or knit cop-tubes described in thisspecification consists in a metallic flange at the larger end upon theoutside of the cop-tube, pressed and secured upon and over a small ringplaced upon the inside of the larger end of the cop-tube, whereby suchend of the cop-tube is clamped between the two rings and securely heldand prevented from ravelin g or fraying.

In the drawings, Figure 1 is a View of the cop-tube complete; Fig. 2, anenlarged section of the larger end of the same Fig. 3, separate views ofthe clamping-flange ring and inner ring, and Fig. 4 a modification ofthe clamping flange and ring.

A represents the tube proper, B the flange, and O the inner ring.

The clamping-flange B is made out of thin metal, with a body, a, ofabout the size of the cop-tube, over which it is fitted, and with aflange, a, extending outwardly. The ring 0 has also a body, I), of aboutthe size of the interior of the larger end of the cop-tube, with aflange, b, extending outwardly.

The ring 0 is placed inside the larger end of the cop-tube, so that itsflange b distends the same, which projects a little beyond it.

By suitable mechanism which forms no part of this application the flangea of the clamping-flange B is pressed down over both the end of thecop-tube proper and over the flange b of the ring 0, and thus both theclampingflange B and the ring 0 are secured together, with the end ofthe cop-tube firmly held between them, so that it cannot ravel or fray.

In the modification shown in Fig. 4 the clampingring has no body likethat before designated by the letters and b, but the inner ring has abody rather longer than that previously described, and when the two areclamped together both the clamping-flange and the ring are left with abell-shaped mouth, with a space between the clamping-flange and thering, which serves also, by its elastic nature, to assist in holding thetube upon the spindle. This metallic fastening may be a little largerthan the body of the tube at its larger end, so that portion of the tubemay not bind or gripe upon the spindle.

It is apparent that this sort of fastening need not be confined towoven, braided, or knit cop-tubes, or to their larger ends; butisapplicable to a great variety of flexible coptubes of various materials,and to either or both ends of the same.

It is also evident that the inner ring, 0, need not be made of metal, asany other material of suitable strength would answer the same purpose,although possibly not so efficiently.

Having thus described this invention, what is claimed new therein is-- Awoven, knit, or braided cop-tube, with one or both ends secured by theclamping device B O, constructed and arranged substantially asdescribed.

This specification signed and witnessed this 30th day of April, 1879.

ALBERT BALL.
